High Power Laser Diode Is there a laser diode in a cd rom drive from a computer?
i have a laptop that is not being used and it is really really old so it is slow and i want to take it apart but i want to see if there is a diode in there so i can build my own high powered laser
and if there is where is it
Yes, there is a laser diode in the CD rom drive. However, it will probably be fairly low power. If it is burner, it will be much higher power. You should be warned that there is a good chance it is an infrared laser that is invisible to your eye but can easily cause eye damage if used improperly. Infrared lasers cause most laser eye injuries. If it is not infrared, it will be red. All cd and dvd drives and burners are not meant to be taken apart and can be dangerous to an inexperienced laser user. I would probably pass on this idea as there is a 95% chance you will either be totally unimpressed or blind someone with this endeavor. And remember that if a laser is powerful enough to cut through something, then the stray reflections from that laser will be way more than enough power to do permanent and instantaneous eye damage.
This book summarizes a five year research project, as well as subsequent results regarding high power diode laser systems and their application in materials processing. The text explores the entire chain of technology, from the semiconductor technology, through cooling mounting and assembly, beam shaping and system technology, to applications in the processing of such materials as metals and polymers. Includes theoretical models, a range of important parameters and practical tips.

In this book, the design of InGaN LDs structures including multi quantum wells (MQWs) active region device are described and investigated by integrated system engineering technology computer aided design (ISE TCAD) device simulator. The parameters of the LDs structures are varied and optimized for high performance. This optimization study involves aspects such as thickness of active region, doping, thickness of stopper layer region, thickness of quantum wells and quantum barriers, number of quantum wells and several approaches to improve and achieve high efficiency, low threshold current and high output power of InGaN LDs. The basic LDs structures treated here are FabryPerot type InGaN double heterostructure (DH), separate confinement heterostructure (SCH) and multi quantum wells (MQWs).High performance LD has been obtained by using multi quantum wells incorporated with the optimized parameters. The lowest threshold current, higher external quantum efficiency and characteristic temperature are obtained when the number of InGaN well layers is two, at our laser emission wavelength of 415 nm, which is related to the problem of inhomogeneous carrier.

This book basically gives the over view about The properties of erbiumdoped fiber amplifier (EDFA) such as gain and noise figure have been studied. By determining the characteristics of the 980nm, 1480nm 1550nm laser sources and ASE (amplified spontaneous emission) at the output of the amplifier used to determine the gain and noise figure of EDFA. This model allows to follow the signal (1550nm), pump (980nm) and ASE as they propagate along the fiber and determine population inversion .The both forward and backward propagation ASE are important in determining the overall gain and noise figure. For the amplification of more than 80 channels the DWDM (Dense Wavelength Division Multiplexing) has required CBand (15251565)nm and LBand (15651610)nm EDFA.We show that a flat gain spectrum can be achieved in the range from 1565 to 1610 nm when the EDF length, pump power and pump configuration are appropriately chosen. Special care must be taken when selecting the EDF length.

Enterococc faecalis considered to be the mostresistant bacteria of the root canal, in the presentstudy we used two types of root canal disinfectant toshow their effect on this type of bacteria, the firstis the diode laser and the second NaOCl solution withspecial concentrations and times. the study conductedon human decoronated extracted teeth, adjusted with13mm root length, filled with a suspension of E.faecalis, Samples were divided into 14 groups eachgroup consisted of 10 prepared roots, sixty sampleswere irrigated with NaOCl solution at differentconcentrations (0.5, 2.5 and 5.25) at twoselected times (2 minutes and 5 minutes) for eachconcentration.Sixty samples were irradiated at different powers (2W, 2.5W and 3W); each power at thetotal irradiation time 30 and 60 seconds. Whencomparison was made between NaOCl irrigant and diodelaser in a combination among differentconcentrations, powers and times the result showedthat 5.25 NaOCl at both 2 minutes and 5 minutes hadthe highest antimicrobial effect with no significantdifferences from 3W laser / 10 sec (6 cycles) butsignificantly different from 3W / 5 sec (6 cycles).

Okay, just about everyone has a red laser pointer. Heck, we even sell a fine one here at ThinkGeek. But, we're pretty sure you want to be a superior geek - and doing it with a green laser is the way to go. This pointer is significantly brighter (about 50 times) than a red laser pointer and because of its unusual color it is much more noticeable. I mean come on, a 532 nm green laser wavelength is obviously superior to a laughable 650 nm red laser wavelength. And unlike a red laser, the green beam itself can be seen in mid-air in dark conditions, not just the laser beam dot. This allows the green laser pointer to be used for pointing to star constellations (skypointing) and also just generally look cool as hell. The green laser beam dot can be seen at much greater distances than with a red laser pointer. Since green direct injection laser diodes aren't readily available, this pointer is based on the use of Diode Pumped Solid State Frequency Doubled (DPSSFD) laser technology. A high power IR laser diode at 808 nm pumps a tiny block of Nd:YVO4 generating light at 1,064 nm which feeds a KTP intracavity frequency doubler crystal to produce the green beam at 532 nm. Features of this unit include: Very bright green laser at 532 nm wavelength Output power of Range of approximately 9,000 ft (2600 m) in darkness 1.1 mm beam diameter at source Momentary push button switch Solid, heavy duty construction Constant wave output (as opposed to pulse output) Takes 2 "AAA" batteries (not included) Can be used for skypointing, projection on low clouds, signaling, highlighting potential explosives Dimensions: 5.6" x .5" dia 90-day warranty Available in Black or Silver color Interested in quantity discounts or custom logo imprinting?
